2.7A loading to +12V O/P and DC O/P voltage is 12V +/- 1.2V,
2.1A loading to 5V O/P and DC O/P voltage is 5V +/- 0.25V
3.2 Check voltage at (B)
5V O/P should be within the range 5V +/- 0.25V
12V O/P should be within the range 12V +/- 1.2V
4. Display Adjustment
4.1 Access to factory mode (RS232) in auto-alignment system
The communication protocol switches to RS232.
4.2 Auto color adjustment (B)
Apply a 640*480/60Hz signal with 16 level grey test pattern, set
brightness control at 100%, and contrast control at 50%. Adjust
the R.G. B. offset, and gain to calibrate the color smoothly and
64-grey level distinguishable.
4.3 Adjustment of WHITE-D (B)
Apply a 1280*1024 / 60Hz signal with white pattern, set
brightness control at 100%, and contrast control at 50%. Adjust
the R, G, B Sub-Gain, for the screen center, the 1931 CIE
chromaticity (X, Y) co-ordinates shall be
